.SYNOPSIS
    Query Microsoft Graph API
.PARAMETER EnableInFilter
    Enables in filter by in on ids for requried uniqueIds; $filter={previous filter} and id in ({csv with ids})
    Should be more flexible than GetByIds, scalability to be tested to eventually replace getbyids
    This filter is currently experimental and will be subject to future change (move to DisableInFilterBatching).
.EXAMPLE
    PS C:\>Get-MsGraphResults 'users'
    Return query results for first page of users.
.EXAMPLE
    PS C:\>Get-MsGraphResults 'users' -ApiVersion beta
    Return query results for all users using the beta API.
.EXAMPLE
    PS C:\>Get-MsGraphResults 'users' -UniqueId 'user1@domain.com','user2@domain.com' -Select id,userPrincipalName,displayName
    Return id, userPrincipalName, and displayName for user1@domain.com and user2@domain.com.
